4-Hydroxy-2,2′,3,4′,5,5′,6-heptachlorobiphenyl

Description:

4-Hydroxy-2,2′,3,4′,5,5′,6-heptachlorobiphenyl, with CAS number 158076-68-7, is a chlorinated biphenyl compound that belongs to the class of polychlorinated biphenyls (PCBs). This substance is characterized by the presence of multiple chlorine atoms attached to a biphenyl structure, which consists of two phenyl rings connected by a single bond. The "4-hydroxy" designation indicates the presence of a hydroxyl (-OH) group at the para position of one of the phenyl rings. This compound is known for its persistence in the environment, potential bioaccumulation in living organisms, and possible toxic effects, including endocrine disruption. Its physical properties, such as solubility and volatility, are influenced by the degree of chlorination and the presence of the hydroxyl group. Due to its environmental and health concerns, 4-Hydroxy-2,2′,3,4′,5,5′,6-heptachlorobiphenyl is subject to regulatory scrutiny and is often monitored in environmental studies.
